D815EEA drivers

i have integrated video with this mobo, and i discovered i only have 4 mb of shared vid memory. im pretty sure that im able to increase it (i have an older mobo which can do that), but i cant do it thru the bios. i cant find the option to do it through windows either.
im thinking upgrading the drivers might help, but i cant find them anywhere on the intel.com site. i go into the D815EEA's section, but it only gives me a BIOS flash and a monitor utility.
anyone know where to find the drivers?

I'm a bit confused, I assume you have on-board video that you have dis-abled, seeing as you list a GF4 MX vid card (with it's own memory). The shared video memory of the mobo should no longer apply or be of any concern.
